feat(tymux): send CWD before honoring client DETACH in daemon
In the daemon's per-client read handler, the TSRV_MSG_DETACH case now
readlinks /proc/<inner-shell-pid>/cwd and ships the path to the
disconnecting client via TSRV_MSG_CWD before closing the fd. On any
readlink failure, the daemon sends zero-length CWD payload (protocol
sentinel for "no cwd available"). Native Terminology clients use this
to spawn fresh shells at the same working directory after detach,
preserving the user's filesystem location. The readlink executes while
the inner shell is still alive, so /proc lookup is reliable.
